motion to the beam of the machine during the winding of the threadsthereon so that the threads willlay on toprof each other at an angleinstead or parallel to each other, to the end that warp streaks will beeliminated.l

As is well known in weaving' the present tendency is for the warpsections to leave streaks in the cloth due to notvbeing evenlydistributed on the beam. In accordance with the present invention aneven distribution of the warp sections and the winding thereof on thebeam will be accomplished so that the streaking above referred to willbe lessened if not entirely obviated.

A further obj ect-of the invention is to eliminate the present practiceofv rolling stiff cardboard every fewrevolutio-ns of the beam in orderto keepthe warp ends straight and allow a uniform tension on all ends inweaving as is now required in the beaming of finer yarn. The objectionto the use of such cardboard is that the same increases the diameter ofthe warp beam for a given length warp to such a proportion thatdithculty is encountered in the 'use of the warp in a loom.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein:

Figure 1 is an enlarged sectional View illustrating the application ofthe attachment to the warp beaming machine.

Figure 2 is a View partly in section and partly in elevation showing themanner in which the thrust wheel or gear is mounted in accordance withthe present invention.

Figure 3 is an elevational View of a cam disk and a supporting platetherefor.

Figure 4 is a plan view of the body of wheel.

Figure 5 is a fragmentary sectional view through the rim of the thrustwheel, a retaining rivet being also shown separate from the wheel.

Figure 6 is an elevational view of a portion of the rim of the thrustwheel.

Figure 7 is an elevational view of a frustreconical roller, pin andbearing sleeve therefor,

and

Figure 8 is a perspective View of a bushing to be hereinafter more fullyreferred to.

Referring to the drawings by reference numerals it will be seen that I Iindicates generally the thrust a portion of the warp beaming machinewhile the reference numeral l2 indicates a portion of the beam core. f

In accordance with the present invention the beam :core I2 is mountedfor free longitudinal "-5 play in its bearings and at one end isprovided with a reduced portion ma.

The attachment is indicated generally by the reference numeral I3 and inthe present instance comprises a'plate I that is secured to the frame 10of the warp beaming machine through the inedium of boltsor otheriastening elements i5. The plate is provided with upper and lowerilanges I6,'and confronting the plate it is a second plate v I'Irwhichis also provided with upper and lower l5 flanges I8 which are secured tothe iianges. It of the plate- I i by a bolt and nut means IS.

Intermediate their ends the plates It, l'i are provided with bearings2&3, 2 I. These bearings accommodate the end 52a of the beam core asshown 20 in Figure l. On the innerer confronting faces thereof theplates It, I5 are provided with centre recessesvZE in which are fittedcam plates 23 that are secured in xed position through the' medium ofbolts or other fastening elements 245. Ontheir 25 opposing orconfronting faces the camplates 23, which plates are identicalinconstruction, are provided with cam humps 25. 'Ihe cam plates 23 are soangularly adjusted that the humps 25 on one plate confront the spaces onthe other plate 3o between the cam humps of the second plate, or inother words the cam humps are arranged in alternation.

. Mountedon the end i201l of the beam core to rotate the beam core, andarranged between the cam equipped faces of the plates 23 is a sprocket vor thrust wheel over which is trained a driving chain 26 for driving thesprocket and consequently the beam core I2.

The aforementioned thrust wheel or sprocket comprises a body 2l ofspider form provided with a hub 28 the bore of which has its endsoppositely v tapered for accommodating the tapered ends 29 of bushings30 that snugly fit about the end I2a ofV the beam core and extend intothe bearings 20, 2l. The bushings 30 are held in position on the end I2@of the beam core between the shoulder 3| formed on the beam core and anut 32 threaded on the free end of the part I2a of the beam core.

A binding of the elements just referred to will be such that drive willbe transmitted from the thrust wheel or sprocket to the beam core I2.

In addition to the body 2l just referred to the thrust wheel or sprocketincludes a removable rim 33 that is provided with suitable sprocket 55Ament the body 21 on its periphery is provided at intervals withtransverse notches 35 while the rim 33 on its inner edge is providedwith notches 'Y 35 that mate with the notches 35 so as to accommodaterivets 31, which rivets have their ends upset so as to be positivelysecured in place and to .hold the parts 21 and 33 of the sprocket wheelassembled,

Arranged in the spaces of the body 21 between the webs 38 of said bodyare substantiallyfrustroconical rollers S9, and for these rollers thereare provided suitable pins or stub-shaftsy 40 the respective oppositeends of whichare fttedinto 4sockets 4i and apertures 42 provided inthebody 21 of the sprocket and as will be clear from a study of Figurel, Y j j As also will be clear from a study of Figure 1 opposite each ofthe openings 42 the rim 33 of the sprocket is provided with an oil hole43 whereby lubricant may be introduced into an oil Ypasv sage 44provided in the pin 4G and opening at one end and at one side of thepin;

The pin 45 for each'roller 39 extendsthrough spaced bushingsor sleeves45 arranged within the bore of the roller 39. The sleeves 05 are spacedabove and below the lateral outlet for the oil passage 44 so as toprovide between the confronting ends of the bushings or sleeves 45 anoil well to accommodate the lubricant. Y

From the above Yit will be apparent that as the Ythrust wheel orsprocket rotates the core beam I 2 will also be caused to rotate or-`revolve. As the sprocket wheel rotates the rollers 39 successivelyengage Vthe cam humps 25 on the plates 23 in .a1- ternation with theresult that during rotative movement thereof the core beam l2 is alsocaused to reciprocate longitudinally.

It will be understood that as the yarn isbeing wound on to the beam ofthe machine .the said beam as just Yexplained will be rotating Yandreciprocating with the result that the threads will be caused toA layVon the beam in such a manner that the threads will lay on Ytop of eachother at an angle instead of parallel to each other.

It will also be apparent that this invention will not interfere with theusual method of beam warping in textile establishments. As is well knownpresentl methods consist in rst winding a certain number of threads ona'reel to form a section, and when enough sections have been formedon'the reel, these sections are then wound on to the beam. With thisinvention all the sections may be wound at the same time on to the beam,and with this invention in use there will be an even distribution of theyarn over the beam with the result that the tendency of these warpsections topleave streaks in the cloth will be eliminated as will alsothe practice, as hereinbefore mentioned, when ner yarn is used, of Yrolling stiff cardboard every few revolutions of the beam inV order tokeep the warped ends straight and allow a uniform tensionvon all ends,

in weaving. 1 Y
